Oil – Gas Grade Gilsonite:
Oil and Gas Grade natural bitumen, in drilling fluids or liquids perform a diversity of operations that influence the drilling rapidity, efficiency, safety also the cost. An important characteristic of gilsonite that make it noteworthy for drilling fluid usages is softening-point temperature. In addition, there are many types of drilling fluid systems includes: water base, oil base, stable foam and air or gas base muds. In water-based muds, it uses as shale-stabilizing additive. It`s difficult to evaluate unless tested at or above its softening point. In oil-base muds, it uses as a FLC agent.
Furthermore, main drilling mud additives include viscosifying factors, fluid loss control agents, corrosion inhibitors also drilling fluid dispersant cement additives are considered to be critical inputs in supplementation of any oil and gas well.
Oil – Gas Grade gilsonite Specification:
Natural Bitumen other uses:
Gilsonite also used in cementing slurries. It uses to provide density control, scouring action for mud removal, and to support compressive strength development. Its reaction with shaleis improving cement bond, development and strength. Wellbore is primary hole, which final well will made. Also, it can encased by steel or cement. Depending on situation, may not be encased. In oil wells, it`s necessary to encase wellbore by cement. Adding gilsonite during Oil well cementing enhances isolation characteristics while decreasing vertiginous Gas flows. These characteristics can results more effective mud removal which also enhances the environmental factors. Drilling environmental regulations are getting more and stricter around the world.
